The jazz age essay

American cities changed drastically during the 1920 s
because of factors above and beyond those related to the automobile.
First, the decade saw millions of people flock to the cities from
country farmlands; in particular, African Americans fled
the South for northern cities in the post–World War I black migration. Immigrants ,
especially eastern Europeans, also flooded the cities. As a result
of these changes, the number of American city dwellers—those who
lived in towns with a population greater than 2 , 500 people—came
to outnumber those who lived in rural areas for the first time in
. history.
